SUET: Are raccoons the culprits?

In recent weeks I've lost three suet holders. Not just the suet cakes, mind you, but the entire feeder. I bought yet another feeder but this time securely affixed to the tree with some serious hardware. I'm resolving to purchase and install a critter-cam so I can see exactly what the hungry nocturnal creatures are doing in my backyard. I suspect raccoons. Even though the suet is supposed to be for the birds, I can't help admiring the persistence and ingenuity of the feeder-thieves.
